Chlorinated hydrocarbons in the marine environment. A report prepared by the Panel on Monitoring Persistent Pesticides in the Marine Environment of the Committee on Oceanography
Panel on Monitoring Persistent Pesticides in the Marine Environment, E.D. Goldberg, P. Butler, P. Meier, D. Menzel, G. Paulik, R. Risebrough, L.F. Stickel
1971, Book
SUMMARY AND RECOMMENDATIONS : The oceans are an ultimate accumulation site for the persistent chlorinated hydrocarbons. As much as 25 percent of the DDT compounds produced to date may have been transferred to the sea. The amount of DDT compounds in the marine biota is estimated to...
Status of correlation of Quaternary stratigraphic units in the western conterminous United States
P. W. Birkeland, D. R. Crandell, G.M. Richmond
1971, Quaternary Research (1) 208-227
Deposits of Quaternary age from the Rocky Mountains to the Pacific Coast in the western conterminous United States represent a great variety of environments. The deposits include those of continental and alpine glaciers, glacial meltwater streams, nonglacial streams, pluvial lakes, marine environments, eolian environments, and masswasting environments. On two charts...
Aircraft measurements of microwave emission from Arctic Sea ice
T. Wilheit, W. Nordberg, J. Blinn, W. Campbell, A. Edgerton
1971, Remote Sensing of Environment (2) 129-139
Measurements of the microwave emission from Arctic Sea ice were made with aircraft at 8 wavelengths ranging from 0.510 to 2.81 cm. The expected contrast in emissivities between ice and water was observed at all wavelengths. Distributions of sea ice and open water were mapped from altitudes up to 11...
The sea sled - A device for measuring bottom profiles in the surf zone
E. Reimnitz, D.A. Ross
1971, Marine Geology (11) M27-M32
The Sea Sled is a simple, easily constructed device for obtaining relatively accurate and quick bottom profiles in the surf zone. The onshore — offshore motion associated with the passage of waves propels the sled on both its seaward traverse and the shoreward...
Effects of irrigation on streamflow in the Central Sand Plain of Wisconsin
E.P. Weeks, H.G. Stangland
1971, Open-File Report 70-362
Development of ground water for irrigation affects streamflow and water levels in the sand-plain area of central Wisconsin. Additional irrigation development may reduce opportunities for water-based recreation by degrading the streams as trout habitat and by lowering lake levels. This study was made to inventory present development of irrigation in...
Use of time-lapse photography equipment for hydrologic studies
J.R. Beck
1971, Report
This report describes equipment used for recording hydrologic events photographically on a controlled time scale. Equipment used included a 16-mm (millimeter) motion-picture camera, batteries, and associated intervalometer hardware.Variables that affected operation of the equipment, and which were used to turn the equipment on and off upon demand, were sunlight intensity,...
Aerial photographic reproductions
Water Resources Division, U.S. Geological Survey
1971, Report
Geological Survey vertical aerial photography is obtained primarily for topographic and geologic mapping. Reproductions from this photography are usually satisfactory for general use. Because reproductions are not stocked, but are custom processed for each order, they cannot be returned for credit or refund....
Surface water supply of the United States, 1961-65, Part 13. Snake River basin
1971, Water Supply Paper 1934
This volume is one of a series of 37 reports presenting records of stage, discharge, and content, of streams, lakes, and reservoirs in the United States during the 1961-65 water years. Since 1888, when the U.S. Geological Survey first studied streamflow in relation to problems of irrigation, similar records have been obtained at...
